Synbiotic microencapsulation system for probiotic stability in gummies
This innovative dual-layer synbiotic microencapsulation system enhances probiotic stability in gummy vitamins using GRAS ingredients. It combines sodium alginate and gum arabic for superior protection, ensuring viability retention of >10⁷ CFU/g over six months.
Overview
The synbiotic microencapsulation system is designed to significantly enhance the stability of probiotics in gummy vitamin products. By utilizing a dual-layer encapsulation method, this system provides robust protection for probiotics against environmental stressors such as oxygen, acidity, and physical stress. The primary layer is composed of sodium alginate hydrogel beads, which are further reinforced by a secondary gum arabic coating. This approach not only improves probiotic survival but also supports a clean-label, consumer-friendly product.
Technical specifications
- Dual-layer encapsulation: Probiotics are first encapsulated in sodium alginate beads via ionotropic gelation with calcium chloride. A secondary coating of gum arabic is applied to enhance oxygen barrier properties.
- Synbiotic effect: The encapsulation matrix includes fructooligosaccharides (FOS) and polyphenols (POL), which act as prebiotics to promote probiotic viability.
- Probiotic strains: The system targets robust strains such as L. rhamnosus GG and B. lactis.
- Gummy formulation: Encapsulated probiotics are incorporated into gelatin- or pectin-based gummies, optimizing for sensory quality and compatibility.
- Viability target: Ensures probiotic viability retention of over 10⁷ CFU/g for a minimum of six months.
Technology readiness level
Currently at Technology Readiness Level 3, this system has undergone initial experimental validation. Future studies will focus on stability, sensory attributes, and scalability to benchmark against conventional formulations. The goal is to demonstrate reduced probiotic losses and compliance with label claims using GRAS materials and scalable processing approaches.
About University of Georgia
The University of Georgia is a comprehensive public land‑grant research university serving a large student body across multiple campuses, known for applied scholarship and community partnership. Industry partners access core facilities and pilot‑scale capabilities—including the Food Product Innovation and Commercialization Center—for prototyping, scale‑up, and product validation. A downtown Innovation District and a statewide Cooperative Extension network link campus expertise to companies across Georgia, while proximity to Atlanta’s corporate and logistics hubs lowers barriers to engagement. Research is supported by competitive federal funding from agencies such as NIH, NSF, USDA, and DOE. A dedicated technology transfer office provides IP services, licensing, startup support, and incubator space to accelerate commercialization.
